Webpendently, Nash introduced a similar techniques in 1958 [15]. Subsequently, Moser provided a new formulation of the proof in [14]. Those methods are now usually called De Giorgi-Nash-Moser techniques. The method has been extended to degenerated cases, like the p-Laplacian, rst in the elliptic case by Ladyzhenskaya and Uralt’seva [13].
